Abstract

Structure assurant une compensation simple du défaut de concentricité entre une virole et un roulement. Elle comprend un premier élément de bâti 42, possédant une surface annulaire extérieure et une intérieure, dent les centres sont décalés radialement d'une première distance prédéterminée l'un par rapport à l'autre; un second élément de bâti 43, possédant une surface annulaire extérieure et intérieure, dont les centres sont décalés radialement d'une seconde distance prédéterminée l'un par rapport à l'autre ; et un dispositif servant à faire tourner l'un par rapport à l'autre ce premier et ce second élément de bâti pour les amener sur des positions sélectionnées, ceci de façon à réduire de façon importante tout défaut de concentricité existant entre la virole 57 et le roulement 19. Application aux turbomachines.Structure providing simple compensation for the concentricity defect between a ferrule and a bearing. It comprises a first frame member 42, having an outer annular surface and an inner one, the centers of which are radially offset by a first predetermined distance from each other; a second frame member 43, having an outer and inner annular surface, the centers of which are radially offset by a second predetermined distance from each other; and a device serving to rotate this first and this second frame element with respect to each other to bring them to selected positions, this so as to significantly reduce any lack of concentricity existing between the ferrule 57 and the bearing 19. Application to turbomachines.
